Abstract

L’invention concerne un détecteur de particules élémentaires (1) comprenant des dynodes (10) aptes à convertir une particule élémentaire en une avalanche d’électrons, des grilles conductrices (30) aptes à être traversées par des électrons accélérés, et étant chacune définie par un potentiel électrique unique, chaque potentiel électrique unique étant choisi pour que le potentiel électrique unique de ladite grille conductrice (30) soit strictement inférieur au potentiel électrique unique appliqué à la grille conductrice (30) qui lui succède le long de la direction de détection (X),, au moins un capteur de signal (50) apte à mesurer un signal électrique (S) produit par les électrons accélérés lorsqu’ils traversent les grilles conductrices (30), et une unité de commande (90) configurée pour déterminer, à partir du signal électrique (S), une dynode de conversion (18) au niveau de laquelle la conversion de la particule élémentaire a eu lieu. L’invention concerne également un procédé de détection de particules élémentaires. Figure 1The invention relates to an elementary particle detector (1) comprising dynodes (10) capable of converting an elementary particle into an avalanche of electrons, conductive grids (30) capable of being traversed by accelerated electrons, and each being defined by a single electrical potential, each single electrical potential being chosen so that the single electrical potential of said conductive grid (30) is strictly lower than the single electrical potential applied to the conductive grid (30) which follows it along the detection direction (X), at least one signal sensor (50) capable of measuring an electrical signal (S) produced by the accelerated electrons when they pass through the conductive grids (30), and a control unit (90) configured to determine, from the electrical signal (S), a conversion dynode (18) at which the conversion of the elementary particle has taken place. The invention also relates to a method for detecting elementary particles. Figure 1
